摘　　要：欧拉运动学方程的推导,关键是确定本体坐标系与空间坐标系之间的转换关系.通过引进方位矢量可以较轻易地得到反映两坐标系转换关系的转换张量,从而能清晰直观地推导出欧拉运动学方程,而这是有别于传统的推导方法的.For the derivation of Euler kinematic equations,the critical step is to determine the transformation relations between body coordinate system and space coordinate system.It is easier to obtain the conversion tensor that reflects the transformation relations between the two coordinate systems by introducing azimuth vector.Thereby,Euler kinematic equations can be clearly and intuitionally deduced,which is different from the traditional way to make it.

关 键 词：欧拉运动学方程 方位矢量 转换张量
